  B. IDS
  C. PuTTY
  D. IPS
  C. PuTTY

  ---

• Question 552:

  A stateful point to point wireless connection going down for a few hours at a time is MOST likely due to which of the following?

  A. Interference
  B. Configuration
  C. Incorrect MTU size
  D. Incorrect IP
  A. Interference

• Question 553:

  Which of the following a network technician would use to reverse engineer malware and virus?

  A. IDS
  B. VLAN
  C. Virtual Machine
  D. Switch
  C. Virtual Machine

  ---

  Virtual Machine --- even if the VM gets infected, host machine will run as normal.

• Question 554:

  Hubs are differentiated from switches in that between the two, only hubs have:

  A. a single collision domain.
  B. a single broadcast domain.
  C. multiple collision domains.
  D. multiple broadcast domains.
  A. a single collision domain.

• Question 555:

  A technician needs multiple networks, high speeds, and redundancy on a system. Which of the following configurations should be considered for these requirements? (Select TWO).

  A. Routing table
  B. Next hop
  C. Port mirroring
  D. Port monitoring
  E. VLANs
  C. Port mirroring
  E. VLANs

  ---

  Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

• Question 556:

  Which of the following will BEST block a host from accessing the LAN on a network using static IP addresses?

  A. IP filtering
  B. Port filtering
  C. MAC address filtering
  D. DHCP lease
  A. IP filtering

  ---

  IPFilter (commonly referred to as ipf) is an open source software package that provides firewall services and network address translation (NAT) for many UNIX-like operating systems. The author and software maintainer is Darren Reed. IPFilter supports both IPv4 and IPv6 protocols, and is a stateful firewall.

• Question 557:

  Which of the following defines the pinout of an 8P8C eight pin modular jack for a CAT6a cable?

  A. 568B
  B. RJ-11
  C. RJ-45
  D. RS-232
  A. 568B

• Question 558:

  Which two layers of the OSI model make up the TCP/IP model Network Interface layer?

  A. Application and Transport
  B. Transport and Session
  C. Physical and Data Link
  D. Session and Presentation
  C. Physical and Data Link

• Question 559:

  A NAS appliance has had a failed NIC replaced. Now the NAS appliance is no longer visible on the network. Which of the following is the MOST likely cause of the problem?

  A. The network cable connecting the NAS to the network switch is bad.
  B. The network port that the appliance is connected to is assigned to the wrong VLAN.
  C. Port security on the Ethernet switch has disabled the port.
  D. Firewall needs to be updated for the new NAS device.
  C. Port security on the Ethernet switch has disabled the port.

  ---

  As by port security switch find the changes in mac address because nic is replaced so due to security reason switch shut that port.

• Question 560:

  Using source port numbers as a way to keep track of connections is a characteristic of which of the following protocols?

  A. TCP
  B. UDP
  C. NAT
  D. PAT
  D. PAT
